The invention relates generally to scalp treating devices and moreparticularly to a device for applying atreating liquid to the scalp. 7

An object of the invention is to provide" an improved device of thischaracter for applying a heated liquid, such as oil, to the scalp whichembodies a liquid. reservoir of large capacity, and means forcontrolling and regulating the flow of liquid therefrom.

Another object residesin the provision of a novel means for producing apositive flow of liquid from the device to the scalp. In thisconnection, the device is arranged to discharge liquid from a number ofhollow members, which are maintained in spaced relation to the scalpduring operation to prevent the clogging thereof by dandruff or thelike, said spaced relation being such that liquid is withdrawn throughthe members by cohesive action of the liquid once contact thereof withthe scalp has been effected.

A general object of the .invention is to provide such a device which issimple in construction and assembly, is efiicient in operation and whichmay be manufactured and sold at a low cost.

Other objects and advantages will become apparent in the followingdescription and from the accompanyingv drawing, in which:

Figure 1 is an axial section through a device embodying the features ofthe invention.

Fig. 2 is a plan view of the device looking downwardly in Fig. 1.

Fig. 3 is a transverse section through the device taken along the line33 of Fig. 1.

Fig. 4 is a transverse section taken on the line H of Fig. 1.

While the invention is susceptible of various modifications andalternative constructions, I have shown in the drawing and will hereindescribe in detail the preferred embodiment, but it is to be understoodthat I do not thereby intend to limit the invention to the specific formdisclosed, but intend to cover all modifications and alternativeconstructions falling within the spirit and scope of the invention asexpressed in the appended claims.

In describing the present invention, it will Serial No. 566,843.

be considered that the device is particularly adapted for applying oilor oily preparations either in cool or heated condition to the scalp,but it will, of course, be understood that the device is well adaptedfor the application of liquids other than those mentioned.

lVith reference to the drawing, the embodiment of the invention, whichhas been chosen for illustrative purposes, comprises generally anelongated casing 10 having therein a cylindrically-shaped barrel 11which houses and mounts the operative parts of the device. In thisembodiment, the barrel 11 is a metal cylinder arranged to be received inthe outer end of the casing 10 and provided with an internal partitionor wall 12 which divides the barrel into two compartments 13 and 14 ofunequal size. The compartment designated by the numeral 13 is the largerof the two compartments, is disposed within the outer end of the casing10 and constitutes the oil receptacle. Extending radially of the barrel11 from one side thereof is a longitudinally alined row of rods 15 andsmall-bore 5. tubes 16. The bores in the tubes communicate with theinterior of the compartment 13 so that oil may flow therethrough fromthe compartment. 'The arrangement of the tubes and rods will behereinafter more particu- 8Q larly described.

The open face of the compartment 13 is closed in any suitable manner, asby a plug 17 arranged to fit snugly and rotatably therein. Preferably,this plug is fashioned to 5 provide a valve for admitting air to theinterior of the compartment. To this end, the portion 18 of the plugwhich fits within the end of the barrel is provided with an L-shapedbore 19. One end of the bore is arranged to 1 communicate with that partof the compartment 13 which will be an air space when the device isupright in use. The other end of the bore is movable upon rotation ofthe plug into and out of registration with an aperture 20 appropriatelyformed in the side of the barrel. It is preferred that the aperture 20be located in alinement with the row of rods 15 and tubes 16.

The smaller compartment 14 is arranged to receive an electrical heatingunit for increasing the temperature of the oil within the compartment13. One preferred form of heating unit comprises a plug 21 havingelectrical conductors 22 extending in parallelism therethrough. The endsof the conductors are secured. to the opposite ends of a resistance orheating element 23 of conventional construction and these ends of theconducs tors, as well as the entire element 23, are pref. erablyembedded in an insulating plaster or ceramic mass 24. The plug 21 isreceivable within the open face of the compartment 14 and is securedtherein in any suitable man.- ner, as by a screw.

' "The casing 10 is so constructed that the parts may beconvenientlyassembled and disassembled to permit the device to be easily cleaned;Thus, the casing is bisectional and comprises a handle section 25 and ahead section 26, both of'which are preferably formed of fibre, bakelite,or the like. The handle section 25 is of substantial length and, at oneend, has an internal collar 27 secured thereto and arranged to fitsnugly about the end of the barrel in which'the heating unit is mounted.Such means as a pin 28 through the handle section 25, collar 27, andbarrel l1 secures the parts rigidly together. In this assembly, theconductors22 extend rearwardly from the barrel 11 through the handlesection 25 and are supported in spaced parallel relationto each otherand to the handle section by a spider 29 through which the conductorsextend. An electric contact plug 30, carrying leads 31 from a source ofcurrent (notshown) ,is receivable within the end of the handle section25 forengagement with the conductors 22. If'desired, a'reinforci ng thehead section may fit snugly about the adjacent end of the handlesection, as at 34. This enlargement of the head section pr0- vides aheat-insulating dead-air space 35 be- 7 tween the barrel and the headsection 26,

The outer end of the section is held in spaced relation to the barrel inany suitable manner as by a ring 36 interposed between the parts nearthe outer end of the device. A flange 37 onthe' plug 17 extends intoabutting engagement with the end of the head section 26 and normallymaintains the assembly thereof-onthe device. I

b With reference to Fig. 1, it will be noted that the rods 15 and tubes16 have an interspersed relationship. That is to say, in this particularinstance there are severalrods at both ends of the. row, whilethroughout the central part ofthe row, the rods and tubes arealternately arranged. Moreover, it will be seen that the rods are longerthan the tubes.-

every tube,'regardless of how many there may be, is positivelyheld outof engagement with the scalp. I y v p The distance at which the ends ofthe tubes are maintained from the scalp is predeter mined with aconsiderable degree of exacta ness. Thus, at the start of an operation,oil will flow through the tubes and form small globules atthe endsthereof. The spacing between the ends of the tubes and the scalp, whichof course is determined by the difference between the length of thetubes and the rods, should be such that the globules will I come incontact with the scalp. when the ends of the rods engage the scalp.Subsequent movement of the device along the scalp causes the oil to bedrawn through the. tubes by the cohesion of the oil. that the oil willbe applied directly to the scalp, as is desired, without applying morethan a minute amount to the *hair, This action of course occurs when thevent to. the interior of the compartment 13, through the aperture. 29and bore 19, is closed by nonregistration of these. openings. Movementof the plug 17, to. bring the openings more or less intoreg-istratiOn,will vary the rapidity with which oil may flfOW through the tubes.

For convenience in'd etermi nin-g the relationship of the aperture 20and bore. 19, a kerf or notch38 is provided in the flange portion 37'of-"the-plug, which kerf is arranged tobe in alin'ement with the row ofrods and tubes when the aperture20= and bore 19 are exactly in registry.1 v p 7 Means for supporting the-device with the tubes opening upwardlywhen the device is not in usefis preferably provided and? one form, ofsuch means is shown in Fig,- 3 as comprising-a wide, roughly U -shapedbracket 39 secured at its ends to thehead: section 26.

It will; be apparent from the foregoing that a noveldevice for applyingtreating lotions or oils to thesscalp has been provided whlchis capableofbeing; readily assembled and disassembled, is: simple. inconstruction,

It will be seen, therefore,

and which, is: eflifcient inoperation. The heating. unit is located; inan independent compartment separate from. the liquid reservoir, therebypermittingthe liquid reservoir to be of substantial capacity. However,the

juxtaposition of the' heating unit andzfthe 1 liquid reservoirinsuressuflicientheating of the liquid. The amount of liquid delivered by thedevice may be easily and variably controlled by the operator by merelyrotating the plug 17. The liquid delivering tubes cannot become cloggedbecause of the positive spacing of every tube from the scalp by theinterspersed rods. Furthermore, the alternating relationship of the rodsand tubes insures that the liquid will be evenly applied to the scalp.
